HANDSAW BLOWER AND HANGER.

Specification of Letters Patent.

Application filed January 5, 1910. Serial No. 536,467.

To all whom it ma'y concern:

Be it known that I, THOMAS Hnnnre, a citizen of the United States,residing at Hornbrook, in the county of Siskiyou and State ofCalifornia, have invented new and useful Improvements in Handsaw Blowersand Hangers, of which the following is a specification.

This invention relates to attachments for hand saws, and the object ofthe invention is to provide a simple and inexpensive device which may beattached to the handle of any ordinary saw comprising a bulb providedwith a depending tube which bulb, being adapted upon compression to blowthe saw-dust incidental to the movement of the saw upon the board so asto leave the line or scribe which the saw is to follow perfectlydiscernible, the device at the same time being provided with a yokehaving a spike extension whereby the saw may be sustained from anyhorizontal support.

With the above, and other objects in view, which will appear as thedescription progresses, the invention resides in the novel constructionand combination of parts hereinafter fully described and claimed.

In the accompanying drawings there has been illustrated a simple andpreferred em,- bodiment of the improvement, and in which drawings Figure1 is a perspective view showing the improvement applied to a saw and themethod of operating the same. Fig. 2 is an enlarged sectional view uponthe line 2-2 of Fig. 1. Fig. 3 is a front elevation of the deviceshowing the same sustaining a saw upon a support. Fig. 4 is a detailsectional view of the lower portion of the compressible bulb and theupper portion of the tube to which the bulb is connected. Fig. 5 is adetail perspective view of the yoke provided upon the tube.

It is well known in the trade that the lines scribed upon a board to becut frequently become indiscernible through the saw-dust raked by theteeth of the saw upon the said board, so that the mechanic using the sawis frequently forced to stop in his work to remove the saw dust from thescribe in order that he can make a perfectly straight and true cut. Itis the primary object of the present invention to overcome this defectby providing the blower whereby the saw dust may be easily and surelyremoved from the path of the cut saw handle with a removable of the sawby the mere compression of an air bulb positioned adjacent to andadapted to be operated by the thumb of the mechanic when the saw isoperated.

In the accompanying drawing-the numeral 1 designates the saw, which isof any ordinary or preferred construction and 2 the handle therefor. Thehandle 2 is also of the ordinary construction being provided with acentral cut away portion adapted for the reception of the hand of theoperator.

The numeral 3 designates the improved blower. This blower comprisesessentially a flexible air bulb 4, which has formed therein an outletlip or tube 5, and the said lip is adapted for the reception of theupper portion of a preferably metallic tube 6. This upper port-ion ofthe tube 6 is provided with an annular bead or rim 7 which when themembers 4 and 6 are in engagement with each other, as illustrated inFig. 4E of the drawings, engages the inner face of the bulb adjacent itstube or outlet 5. The tube 6 is also provided with a funnel-shapedmember 8 which has its outer enlarged portion provided with an annularbead 9, and the said annular bead is adapted to engage the outer face ofthe bulb 4.- so as to effectively support the tube upon the bulb. Thetube 6 has its lower portion bent inwardly toward the blade of the saw 1so that the same lies.

close to the said saw and the said tube terminates a suitable distanceaway from the teeth of the saw so that when the bulb 4 is compressed theair will be forced through the tube and deflected from the face of thesaid saw.

Integrally formed with, or otherwise secured to the funnel-shaped member8 of the tube 6 is a yoke member 10. This member 10 has its arms 11 and12 extended downwardly a suitable distance so that the said arms may beinserted through the hand opening of the saw handle 2 to straddle thesame. The arm 12, which is positioned farthest from the bulb 4: isprovided with a threaded opening, and the said opening is adapted forthe reception of a threaded retaining element 13, the said element beingscrewed tightly against the face of the handle 2 so as to removablyconnect the device with the handle, and at the same time it will benoted that the tube 6 may be adjusted in any desired relation with theblade 1 of the saw. The lower extremity of the arm 12 is brought to apoint as indicated by the numeral l4, and the said point is adapted tobe inserted Within a suitable support 15, such as the horizontal surfaceof a fence or the like.

From the above description, taken in connection With the accompanyingdrawing, it will be noted that it is merely necessary for the operatorgrasping the saw handle 2 to position his thumb adjacent the bulb 4 andupon compression of the said bulb the air will be forced through thetube 6 so as to scatter and remove the saw-dust upon the board beingoperated upon, and it will be further noted that by providing the arm 12of the yoke with the sharpened point 14: the

saw as well as the device may be effectively sustained upon a suitablesupport, and while I have illustrated and described the preferredembodiment of the improvement, as it now appears to me, minor details ofconstruction, within the scope of the following claims may be resortedto if desired.

Having thus fully described the invention, what I claim as new is 1. Thecombination with a hand saw, of a compressible air bulb provided with ametallic tube, a yoke secured to the tube, a thumb screw for one of thearms of the yoke, and said arm having its extremity pointed,substantially as and for the purpose set forth.

2. The combination With a hand saw, of a flexible air bulb, said bulbbeing provided with a tube extension, a metallic tubular member adaptedto be inserted Within the said extension, said metallic tube having itsupper extremity provided with an annular oifset, a funnel-shaped conemember secured to the metallic tube and havlng its upper extremityprovided with an annular ofi'set adapted to bear upon the outer face ofthe flexible bulb, a yoke member secured to the funnel-shaped member ofthe tube, and means for removably connecting the yoke member to thehandle of the saw.

In testimony whereof I afiiX my signature in presence of two witnesses.

THOMAS HERBIG.
